.l 0 all whom it may concern:

Be it known that we, GEORGE LISPENARD and Sonoiuon K. LIOHTENSTEIN, citizens of the United States, residing, respectively, in. the city of New York, borough of Brooklyn, county of Kings, and State of New York, in the city, county, and State of New York, have invented certain new and useful improvements in Cotton-Grins, of which the tollowing is a specification.

The present case is a continuation of our application for patent, filed on the 4th day of March, 1912 and serially numbered 681,541, to which cross reference will be made herein.

The present invention relates to a cot-ton gin. I

Th object of the present invention is to provide eflicient means for ginning the cotton and for moving the cotton seeds away from the point of ginning when the cotton fiber has been sufiiciently removed therefrom.

Before the invention of the gin shown, in our said copending application the most successful and, in fact, the only successful gin in. use was the saw form of gin wherein a numher of circular saws were mounted to move as a, unit, a space being provided between the several saws suflicient to allow the seeds, when the fiber was removed therefrom, to drop away from the ginning point, and to pass downwardly between the saws. Ribs were provided between the saws on which the seeds fell and by which they were guided to a discharging point. In our said copending application we showed a cylinder form of gin wherein, instead of using a series of saws for removing the cotton fiber from the seeds a cylinder was employed wherein a spiral groove was formed around the periphery of the cylinder and slots ofa particular shape out the spiral thread to form a number of teeth of novel shape and arrangement. That cylinder has proven more successful in ginning cotton than the saw form of gin, because it removes the-cotton from the seedsmore rapidly and without shortening the staple. However, in that and other forms of cylinder gins it is impossible to discharge the cotton seeds from the point of ginning and. away from the ginning cylinder in the same way that the seeds were the term at gin, in

cause of the character of the cylinder and because the ribs could not-be used as in the saw gin.

The object of the present invention is provide means for properly feeding the cotton to the point. of ginning and for deliver-in'g the seeds away from the point of ginning in a gin of the cylinder type. We ac complish the desired result by a novel arrangement of the ginning cylinder, the beater or agitator, and the opposing bar, as will be more fully explained hereinafter.

In the drawings .forming a part of this application, Figure l is a, side elevation of a cotton gin wherein our invention is employed. Fig. 2 is a longitudinal sectional View thereof, Fig. 3 is an end elevation thereof, with the seed board removed, and Fig. 4 is an enlarged sectional view of portions of the cylinder, beater and opposing bar.

In the drawings-we have shown our invention embodied in a gin frame of ordinary construction. Herein the frame 1 consisting of standards 2, ginning box 3- and condenser box 4 support the "various working' parts of the gin.

The ginning cylinder 5 is mounted upon a shaft 6 extending crosswise of the ginning box 3 and journaled in the side walls thereof. The operating force for the several parts 'of the gin is preferably applied to a pulley 7 on the cylinder shaft and the ogerating force for various parts of the gin is directly or indirectly transmitted from the cylinder shaft. The cylinder shaft 6 is provided with a pulley 8 over which travels a belt 9.; and with a sprocket 10 over which travels a chain 11. A beater 12 consisting eta eylindric'al body 13 and radial sookes or t-ators i lalong its length, around its periphery, is mounted upon shaft 15, which also extends crosswise of the ginning box and,,is journaled in the sidewalls thereof; and this shaft -is preferably parallel with. the-shaft (5 of the ginning" cylinder. A sprocket 16 on the shaft is driven iron; the cylinder shaftby the chain 1.1, which.

also travels over the sprocket 10. lit will be A, revolving brush it its-Emotionalon a faces move shaft 18 and is arranged whereby its bristles 19 will wipe the face of the ginning cylinder, beyond the opposing bar, in order to remove the cotton from the cylinder as fast as the latter removes it from the cotton seeds.

In the condenser box beyond the brush, are arranged ordinary condenser rollers for condensing the ginned cotton. The larger roller 20 covered with wire gauze in the usual manner,- is mounted upon a shaft 21 arranged crosswise of the condenser box; while the smaller, gauze covered roller 22 is mounted'upon a shaft 23 parallel with the shaft 21. The smaller roller is loosely journaled in open journals 2st so that it Will ride in contact with the larger roller or with the cotton passing between them. The larger condenser roller shaft 21 has a large gear 25 thereon which is driven by a smaller gear 26 mounted on the shaft- 27. The latter shaft also has a pulley 28 which is operated by the crossed belt 9 which travels around the pulley .8 on the cylinder shaft.'

The brush shaft 18 is operated by pneans of a belt 2.9 which travels over a large pulley 30 on the cylinder shaft, over a pulley 81 on the brush shaft and around an idler 32. A niote board 33 is arranged below the brush and directs the cotton to the condenser roller in the usual n'ianner. With the exception of the cylinder and the beater, the above parts are of the usual construction. I

The ginning inemberb is of the cylinder or roller type as distinguished fronrthe saw type; and preferably it is constructed in ac cordance with the ginning cylinder'shown in'our copending application above referred The beater or agitator it will be observed, is mounted parallel with the ginning cylinder and is revolved in the same direction.

' An opposing bar is arranged in a novel re-' lation to the cylinder and heater, in order to cooperate in securing the desired result.

The opposing bar, which is here shown as a metallic plate 33 supported by a back wall 84,'has a concave or recessed front surface directed toward the heater and preferably curved on an arc the center of which coincides with the axis of the beater. --'1he opposing bar -is arranged substantially to one side of a verticalline drawn through the axis of the ginning cylinder. Its curved front face is separated from the beater sufiiciently to allow the latter to feed the cotton which is deposited in the upper part of the rollbox 35 down to the point of ginning, between the opposing bar and heater. The front edge 36 of the opposing bar is straight, is preferably parallel with the periphery of the cylinder and is separated from it sufiicient-ly to permit the teeth of the ginning cylinder to drawthe cotton fiber past it, but

- not enough to permit the cotton seeds to pass betweenthe opposing bar. and the ginuing cylinder. A fraction of an inch is all this space should be.

With the parts arranged as herein shown, it will be observed that if circles be drawn concentric respectively, with the axes of the ginning cylinder and with the beater, they will intersect at'a point to the right; of a line drawn vertically through the axis of the ginning cylinder. This .is not imperative, but it is very desirable, as will be pointed out. Another way of describing this position is to say, that a straight line drawn through the axes of the ginning cylinder and of the beater will come to one sideof the vertical line drawn through the axis of the ginning cylinder. in any event the edge 36 of the opposing bar comes to the vertical line drawn through the axis of the ginning cylinder in order that the cotton seed can not. follow the ginning cylinder to that part of the periphery thereof which is moving downwardly. It avoids the for mation of a pocket where the seeds might gather and escape the action of the heater or be ground to pieces against the edge of the opposing bar.

In the full eml'iodinient of our invention the edge 36 of the opposing bar comes at least to the line drawn between the axes of the ginning cylinder and the beater. In order to illustrate this on the drawing a dotted line 37 has been drawn between the axes.

The heater is arranged suiiiciently above the ginning cylinder so that. as thecotton is fed downwardly to the point or line of ginning, there will be sufiicient space for the formation of a roll as indicated at 38 in the drawing. The tendency of the ginning'cylinder is to move this roll up to the edge of the opposing bar; while the movcnmnt of the heater in a reverse direction has an opposite tendency. The result of this is to form the seed cotton into a roll and to revolve it at the point or line of ginning, i. 0., at the front edge of the opposing bar.

When the ginning cylinder is revolved, "its teeth, passing the opposing bar, will comb the cotton from the seeds and will carry it past the opposing bar; after which the cotton will be removed from the cylinder by the brush and will be delivered to the condensing rollers in the usual manner. The seeds can not pass between the cylinder and opposing bar, and in a cylinder form of gin they will contact with the outer periphery of the cylinder. The cotton and seeds forming the roll 38 will be continuously acted upon by the cylinder teeth and the seeds will finally be stripped of their cotton fiber. hen the cotton has been combed from the seeds the latter will become more or less disentangled from the roll and they will be beaten outwardly from the roll by the action of the heater; and they will be thrown against the seed board 39 or downwardly upon the-board 40.

By arranging the ginning cylinder, beater and opposing bar in the relation here shown we are able to properly and rapidly discharge the seeds after the cotton fiber has been removed therefrom. In the present arrangementthere is no pocket formed Wherethe seeds can lodge on the downwardly moving portion of the periphery of the cylinder, and Wedge against the opposing bar and be ground to pieces by the cylinder-poi escape the action of the beater. On the other hand the present arrangement prevents the beater from jan'uning the seeds against the cylinder and forci'i'lg them against the cylinder in such a manner as to cause theseeds to be cut to pieces. On the contrary, thebeater forcesv the seeds away without injury as soon as the cotton has been removed therefrom and it also helps to revolve the roll of cotton.

Having described our invention, What we claim is:

1, In a cotton gin, the coi'nbination of a revoluble ginning cylinder, an opposing bar having a concave or recessed front surface and a substantially straight opposing edge, said bar being arranged substantially to that side of a vertical line drawn through the axis of the ginning cylinder which is above the descending portion of the cylinder, and having its opposing edge extending at least to the-said vertical line, a revoluble beater above the cylinder and spaced therefrom sufliciently to form a substantial cot ton roll, and cooperating with the opposing bar and cylinder, and means for revolving said cylinder and beater in the same direction.
